今日pycharm上配置python遇到的几个坑_pycharm is not in the subpath of

1.  pip更新问题

You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

   使用以下命令
   pip uninstall pip 

   easy_install pip

   注意windows系统变量里设置的python，很多时候终端命令下屡次反复更新不成功是因为使用的系统变量的那个python环境。

2.python安装cv2出现如下错误：Could not find a version that satisfies the requirement cv2 (from versions: )

   最后用下面的命令安装成功    pip install opencv-python

3.安装face-recognition时报错CMake must be installed to build the following extensions: dlib

首先下载CMake安装，然后再

pip install dlib 

这个安装需要一段时间

然后就可以愉快地pip install face_recognition

对你有用请留个言。
